Diagnosis of major depression Previous history of suicide attempts Depressive symptoms with agitation or distress Burden of medical disease and the presence of a current serious medical condition although this risk may be mediated by a diagnosis of depression Recent stressful life events, especially family discord Lack of social support The presence of a gun in the home Unexplained weight loss Lack of a reason not to commit suicide Presence of a specific plan that can be carried out Rehearsal of the plan The relationship between use of antidepressants and risk of suicide varies with patient age.

A growing body of evidence suggests that the glutamatergic system, known to play a role in neuronal plasticity and cellular resilience, is also involved in the pathophysiology and treatment of MDD.

However, the depression might not meet criteria for major depression because of somewhat atypical features of depression in elderly persons.

The discovery of antidepressant drugs in the s led to the first biochemical hypothesis of depression, which suggested that an impairment in central monoaminergic function was the major lesion underlying the disorder.

There was no significant change in depression symptoms with the ketamine used as an anesthetic during the ECT treatment.

Current antidepressants act primarily on the monoamines serotonin, noradrenaline, and dopamine. The combination of ketamine and ECT has received very little attention in the literature.

The high was short-lived, however: Regulation of cellular plasticity cascades in the pathophysiology and treatment of mood disorders: Based on recent reports of rapid antidepressant effect of single dose ketamine in MDD patients,3,4 the authors of this case report reviewed the information available with the patient and obtained her consent.

Biology of depression

Recent research indicates that changes in the function and effect of these neurotransmitters and how they interact with neurocircuits involved in maintaining mood stability may play a significant role in depression and its treatment.

I will nap and then I wake up feeling refreshed for about an hour and then it comes back after that. Abused substances can also increase risk of major depressive disorder, such as cocaine, amphetamine, narcotics, and alcohol.

Maintenance Ketamine Treatment Produces Long-term Recovery from Depression

I wonder if she would have been there had her favorite song been something else. In an MRI genetic study, Frodl et al found that patients with major depression who carried the S allele of 5-HTTLPR and had a history of childhood emotional neglect had smaller hippocampal volumes than patients who had only one of those factors.

Major depressive disorder

My kids are still pretty young though, maybe some day. During this time patients are exposed to the morbidity and potential mortality from this common and disabling illness. Not getting sufficient dietary or supplemental magnesium during medical or depression treatment for stress related disorders such as anxiety and depression is bound to fail.

Rapid antidepressant effect of ketamine anesthesia during electroconvulsive therapy of treatment-resistant depression: My doctor is so headstrong about increasing my dose that he will not even prescribe me a 50mg pill so that I can split it in half anymore, let alone simply prescribe me a 25mg pill.In older adults depression may manifest more subtly as they tend to be less likely to admit to feelings of sadness or grief and medical illnesses which are more common in this population also contributes or causes the depression.


One biological account for depression is that biochemical factors are involved; the view indicates that depression is caused by a deficiency of neurotransmitters; norepinephrine and serotonin.

Norepinephrine levels in the brain are often low in depressed patients. The understanding of migraine pathophysiology is advancing rapidly. Improved characterisation and diagnosis of its clinical features have led to the view of migraine as a complex, variable disorder of nervous system function rather than simply a vascular headache.

Major depressive disorder has significant potential morbidity and mortality, contributing to suicide, incidence and adverse outcomes of medical illness, disruption in interpersonal relationships, substance abuse, and lost work time.

Depression may be related to abnormalities in the circadian rhythm, or biological clock. For example, rapid eye movement (REM) sleep—the stage in which dreaming occurs—may be quick to arrive and intense in depressed people.

REM sleep depends on decreased serotonin levels in the brain stem, and is impaired by compounds, such as antidepressants, that increase serotonergic tone in brain stem.
